For sale are 16 assorted handmade buttons that have been decoupaged with vintage worldwide postage stamps.  These are adhered to a strong cardboard and they have a coating of clear water-based gloss to make them even more durable.  These are not for clothing but for paper crafts, mixed mosaics, junk journals, cards, scrapbooks.  They lie very flat and are about 1/16" in thickness.  The size is 5/8". 

These are lightweight and flat and I can ship them inexpensively in a regular first class envelope.  There is no tracking with this method.
